IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. [76,983, dated May 2,1876; application filed April 3, 1876.

drawings, and tolthe letters of reference marked thereon, which form apart of this specification. I

' It is well known that coal-oil or other lamps are apt to overflow ordrip, the oil thus liberated running down the outside of the body of thelamp, thus soiling its supporting-standard, and sometimes extending tothe table uponavhiclnthelamp stands, thus becoming a source of greatannoyance.

The objec of this invention is to construct alamp in such manner as toavoid the objectionable results growing out of this overflow or dripmore effectually than has hitherto been done, and to accomplish anotherdesirable effect, which will be hereinafter fully explained.

In the drawing, which is a vertical section of a lamp embodying myinvention, A is an outer globular shell or casing, made, by preference,in a form somewhat resembling an urn, or of other ornamental design, andadapted to receive the body or oil-receptacle B, which supports theburner. The shell A has a socket, a, in which a hub, boss, or similar,

' screwed, soldered, cemented, or otherwisesecured to theupper part ofthe shell, and provided with a number of perforations, c D is anupwardly-projecting flange around the upper portion of the shell. Thisflange may be formed upon the plate 0, or it may be formed of theedge ofthe shell by setting the vided horizontally at or near a point indicatedby w, in which case the outline of the shell may conform more closely tothat of the lamp when it is thought pest to make the latter more nearlyspherical than the one shown in the drawing, although, in practice, Iprefer substantially the construction of parts represented.

The neck of the lamp projects upwardly through the plate 0, and has acollar, E, attached to it, the burner being screwed into this collar; ora non-conducting ring or collar inay be interposed between the burnerand the collar E. O is a non-conducting collar arranged upon the collarE of the body, and between said collar or the neck of the body B and theplate 0. Oollar C may be made with a flange, c, of greater diameter thanthe central opening through the plate, and thus held in place by theother parts; or it may be screwed into the plate or upon the collar E.As the air below plate 0 will become sometimes a little heated fromcollar E, and consequently rarefied atthis point, it will rise,

and colder air will pass in through the openings near the outer edge ofthe plate, thus keeping up a circulation of air within the shell, andpreventing undue heating of the parts.

Any oil which escapes from the body of the lamp will, under ordinarycircumstances, pass through the plate 0 into the shell A, instead offlowing down upon the outside of the standard, as it does in lamps whichhave no inclosing shell or casing. What I claim isv 1. In a lamp, thecombination, with the body or oil receptacle, of an inclosing case orshell, having a perforated removable top or' plate, substantially as setforth 2. The combination, with the body B, of the shell A, the plate 0,and the flange substantially as set forth.

3. The combination, in a lamp, of a body or my own I aflix my signaturein presence of oil-receptacle, a shell which surrounds the twowitnesses. body, and a non-conducting ring, or collar arranged betweenthe neck of the lamp and the STEPHEN NEWTON top or 'upper plate of theshell, substantially Witnesses: as set forth.

In testimony that I claim the foregoing as AMOS B. KENT.
